[0022] Specifically, the tank body 100 is used to contain the recovered metal and the reaction reagent, the reaction reagent is used to react with the recovered metal to form the copper particles floating on the surface of the reaction reagent, it should be noted that the recovered metal is the metal waste doped with copper particles, which contains different types of metal particles, in this embodiment, the reaction reagent is introduced into the tank body 100, so that the reaction reagent can react with the recovered metal, and the copper particles in the recovered metal can float to the surface of the reaction reagent, it should be noted that the flotation method in the prior art is used, and the reaction reagent can use the collector in the conventional technology.

[0023] The scraper assembly 200 includes a plurality of first scrapers 210 rotatably connected to the top edge of the tank body 100, the first scraper 210 is used to scrape the copper particles floating on the surface of the reaction reagent towards the direction of the storage shell 400, so as to separate the copper particles from the recovered metal and scrape them into the storage shell 400 for collection. The stamping assembly includes a plurality of stamping nozzles 300, the plurality of stamping nozzles 300 are circumferentially spaced apart along the bottom of the tank body 100, and the output direction of each stamping nozzle 300 is towards the top edge of the tank body 100, so that the plurality of stamping nozzles 300 form a plurality of interlaced stamping gases in the tank body 100, so as to disperse the recovered metal gathered in the tank body 100 into metal particles by the plurality of stamping gases.

[0024] In the specific operation process, first, the recovered metal and the reaction reagent are introduced into the tank 100 for reaction to separate the copper particles in the recovered metal and float to the surface of the reaction reagent. Since the recovered metal and the reaction reagent, the hydrophobicity of the copper particles is significantly enhanced, and the copper particles may be aggregated due to the hydrophobic force to form a metal group, and the metal group also includes other metal particles. The reaction time is longer, and the punch assembly and the scraper assembly 200 of the present application are used to input the punch gas through the plurality of punch nozzles 300 after starting the punch assembly, and the output direction of the plurality of punch nozzles 300 is towards the top edge of the tank 100, so that the plurality of punch nozzles 300 form a plurality of interlaced punch gases in the tank 100. The interlaced punch gas can disperse the agglomerated recovered metal into metal particles, so that the copper particles can quickly react with the reaction reagent and float to the surface of the reaction reagent. Finally, the copper particles floating on the surface of the reaction reagent can be scraped towards the storage housing 400 by the scraper assembly 200, so that the copper particles are separated from the recovered metal and scraped into the storage housing 400 for collection. Through the above arrangement, the problems of long reaction time and low recovery efficiency in the prior art can be solved.

[0025] In some preferred embodiments, in order to facilitate the recycling of copper particles, please refer again to Figure 1 As shown in the figure, the storage housing 400 can be inclinedly sleeved on the top of the tank 100, and has a discharge passage at the bottom end of the inclination, so that the operator can quickly collect the copper particles.

[0026] In addition, in some actual cases, since the tank 100 will have some precipitated recovered metal, in order to realize the recovery of all copper particles in the recovered metal, in the present example, the recovery device further comprises a first-stage spiral separation passage 500 having at least two first discharge ports 510. The first-stage spiral separation passage 500 is used to communicate with the tank 100, so that the recovered metal precipitated at the bottom of the tank 100 is transmitted along the spiral path of the spiral separation passage to separate the copper particles in the recovered metal from the copper-containing mixed particles.

By opening the valve, the recycled metal deposited at the bottom of the tank body 100 can be transported to the primary spiral separation channel 500 for primary spiral transmission. Since the density of copper particles is high, that is, the density of copper particles is greater than that of other metal particles in the recycled metal, at this time, the copper particles in the recycled metal can be spirally transmitted along the inner side of the primary spiral separation channel 500 by utilizing the density difference, while the copper-containing mixed particles will be spirally transmitted along the outer side of the primary spiral separation channel 500, thereby separating part of the copper particles in the recycled metal, and after the separation is completed, the copper particles can be transported through a first discharge port 510, while the copper-containing mixed particles will be transported through another first discharge port 510.

[0029] Specifically, the copper-containing mixed particles transported by the first discharge port 510 will be transmitted from the bottom to the top by the material transmission assembly 600, and the copper-containing mixed particles will be separated again by the secondary spiral separation channel 700. By utilizing the density difference between the copper particles and the non-copper particles, the copper particles can be spirally transmitted along the inner side of the secondary spiral separation channel 700, while the non-copper particles will be spirally transmitted along the outer side of the secondary spiral separation channel 700. The secondary spiral separation channel 700 can completely separate the copper particles and non-copper particles in the copper-containing mixed particles, and finally the copper particles and non-copper particles will be transported through the two second discharge ports 710, respectively.

The second driver 220 is used to drive the driving shaft 230 to rotate, wherein a plurality of first scrapers 210 are circumferentially spaced apart on the driving shaft 230, and specifically, the second driver 220 can adopt a servo motor in the prior art.

[0034] In addition, since the recovered metal may be attached to the inner wall of the tank 100, in the present embodiment, the scraper assembly 200 further comprises a plurality of transmission arms 240 and a plurality of second scrapers 250. Each second scraper 250 is circumferentially spaced apart from the driving shaft 230 by each transmission arm 240, so that each transmission arm 240 and each second scraper 250 are synchronously driven by the driving shaft 230 to scrape the inner wall of the scraper.

[0035] Since the attachment of metal particles to the inner wall of the tank 100 is uncertain, the transmission arm 240 further comprises a connecting portion 241 and a swing portion 242, the connecting portion 241 is connected to the driving shaft 230, the swing portion 242 is slidably connected to the inner wall of the tank 100, and the second scraper 250 is arranged on the swing portion 242.

[0036] That is, when the second driver 220 drives the driving shaft 230 to rotate, the swing part 242 will swing along the spiral path of the spiral chute 110, so as to increase the scraping area of the second scraper 250 on the tank body 100, and at the same time, the up and down swinging of the swing part 242 and the second scraper 250 can also disperse the agglomerated recovered metal, further improve the recovery efficiency of copper particles, and improve the practicability of the device.
